Terms of Service

Effective date: June 9, 2026

Chapter 1. General Provisions

Article 1. Purpose

These terms set out the rights, obligations, responsibilities, conditions, and procedures governing use of the websites and mobile applications (the “Service”) operated by Athlogic (the “Company”) by users.

Article 2. Definitions

  1. “Service” means all services provided by the Company, including its websites and applications, regardless of the device used, including PCs, mobile devices, and other wired or wireless devices.
  2. “User” means a customer who accesses the Service, enters into a service agreement with the Company under these terms, and uses the Service.
  3. “Member” means a person who registers by providing personal information and may continuously receive information and use the Service.
  4. “ID” means a combination of letters and numbers, such as an email address, chosen by a member and approved by the Company for identification and service use.
  5. “Password” means a combination of letters or numbers chosen by a member to verify identity and protect confidentiality.
  6. “Paid Service” means digital content, including routines, coaching, and video on demand, and other services offered for a fee, including subscriptions.
  7. “Subscription” means recurring payment for access to Paid Services for a specified period.
  8. “Preregistered User” means someone who expresses interest and provides personal information through the website or another channel before launch. These terms apply to such users.
  9. “AI Coaching Features” means personalized routine recommendations and adjustments, exercise explanations, next-week routines, and other coaching information provided using AI models and systems based on workout records, goals, preferences, usage history, and conversations entered by users.
  10. “AI-generated Results” means automatically generated answers, explanations, recommendations, routines, routine adjustments, summaries, analyses, and other content from AI Coaching Features.

Undefined terms follow applicable laws and service-specific guidance, and otherwise general practice.

Article 3. Publication and Amendment

The Company displays these terms, its business name, representative, business address, business registration number, mail-order business registration number, and telephone/email contact information on the initial service screen or a linked screen so users can readily find them.

The Company may amend these terms within the limits of applicable laws, including the Act on Consumer Protection in Electronic Commerce, the Act on the Regulation of Terms and Conditions, the Act on Promotion of Information and Communications Network Utilization and Information Protection, and the Content Industry Promotion Act.

Amendments, reasons, and effective dates will be posted with the current terms on the initial service screen from at least 7 days before the effective date until the preceding day. Changes unfavorable to users require at least 30 days’ notice and separate clear electronic notification, such as email, a message, or a login consent screen.

If the notice clearly states that failing to respond within 7 days (30 days for unfavorable changes) will be treated as consent, a user who does not expressly reject the changes is deemed to agree.

If a user does not agree, the amended terms cannot be applied to that user, who may terminate the agreement. Where special circumstances prevent applying the previous terms, the Company may terminate the agreement.

Article 4. Interpretation

Separate terms or policies may apply to Paid Services or individual services and take precedence where they conflict with these terms.

Unspecified matters and interpretation follow the Act on Consumer Protection in Electronic Commerce, the Act on the Regulation of Terms and Conditions, the Fair Trade Commission’s consumer protection guidelines for electronic commerce, other applicable laws, or commercial practice.

Chapter 2. Formation of the Agreement

Article 5. Formation

The agreement is formed when a user agrees to these terms, applies for membership, and the Company accepts the application. Proceeding with registration or login through social accounts such as Kakao, Apple, or Google is deemed agreement to these terms and the Privacy Policy. Registration and use are available only to persons aged 14 or older.

The Company generally accepts applications but may reject an application or subsequently terminate the agreement in these cases:

  1. Prior loss of membership under these terms, unless re-registration is approved.
  2. Use of a false name or another person’s identity.
  3. False information or omission of required information.
  4. An applicant younger than 14.
  5. Approval is impossible for reasons attributable to the user, or the application violates applicable requirements.
  6. Intended improper or commercial use.

The agreement takes effect when the Company indicates completion of registration during the application process.

Article 6. Changes to Member Information

Members may view and edit their personal information at any time through the profile management screen. Changes to registration information must be updated online or reported by email or another method. The Company is not responsible for disadvantages resulting from failure to report changes.

Article 7. Personal Information Protection

The Company strives to protect personal information under applicable laws, including information and communications network laws. Relevant laws and the Company’s Privacy Policy govern protection and use. The policy does not apply to linked websites other than the Company’s official websites.

Chapter 3. Obligations of the Parties

Chapter 4. Use of the Service

Article 10. Provision and Changes

In principle, the Service operates 24 hours a day, every day. It may be temporarily interrupted for maintenance, replacement or failure of equipment, communications outages, or substantial operational reasons. All or part of the Service may be changed for operational or technical needs, such as a service reorganization. Changes to content, methods, or hours will be announced on the initial service screen at least 7 days in advance with reasons, details, and the date of provision.

Article 11. Health Information and Non-medical Services — Important

Exercise content, routine recommendations, and health information are references for general health improvement and do not replace medical diagnosis, care, or treatment. Users must consider their physical and health condition and avoid overexertion. Those with underlying conditions or abnormal symptoms should stop exercising immediately and consult a medical professional.

The Company is not responsible for injury, deteriorating health, or other loss arising from following exercise methods or using information unless caused by its intent or gross negligence. AI coaching, trainer consultations, recommendations, analysis, and other health features are supplementary references. The same limitation applies to outcomes from overreliance or inappropriate use.

Article 11-2. AI Coaching and AI-generated Results

  1. The Company may provide AI coaching based on workout records, goals, preferences, usage history, and user conversations.
  2. Answers, recommendations, explanations, routines, and other results are automatically generated references. Accuracy, completeness, or suitability for an individual’s health is not guaranteed.
  3. AI coaching is not intended for medical acts, diagnosis, treatment, prescriptions, rehabilitation, disease prevention, or professional medical consultation. Users with pain, injuries, conditions, pregnancy, surgery history, medication use, or other health concerns should consult a medical or qualified professional rather than rely on AI-generated Results.
  4. Users should consider their physical and health condition. Pain, dizziness, shortness of breath, unusual fatigue, or other abnormal symptoms during exercise require stopping immediately and consulting a medical professional.
  5. The Company does not guarantee accuracy, completeness, timeliness, fitness for a particular purpose, or achievement of a particular outcome.
  6. AI usage records may be processed for stability, security, misuse prevention, compliance, error analysis, quality improvement, and support. Categories, purposes, retention, entrusted processing, and international transfers are defined in the Privacy Policy.
  7. Some or all AI features may be limited, suspended, or changed for technical or operational needs or misuse prevention.

Article 12. Information and Advertising

The Company may provide information considered necessary through notices, email, or app push notifications. Members may opt out at any time except for legally required transaction information and responses to support inquiries. Advertisements related to service operation may appear in the Service, website, or email.

Article 13. Copyright and Use Restrictions

Copyright and other intellectual property in Company-created works belong to the Company. Without prior approval, members may not reproduce, transmit, publish, distribute, broadcast, otherwise commercially use, or allow others to use Company-owned information obtained through the Service.

Copyright in member posts belongs to their authors. The Company may use posts without separate permission or payment within a reasonable scope consistent with fair practices under copyright law to operate, display, transmit, distribute, and promote the Service.

Rights and permitted use of AI-generated Results follow applicable laws, these terms, and in-service guidance. Users must respect laws, third-party rights, and these terms. The Company may store, reproduce, analyze, display, transmit, and process AI inputs and results as necessary for service provision, operation, security, error analysis, quality improvement, and support.

Chapter 4-2. Harmful Content Policy

Article 13-2. User-generated Content Policy

Users must not upload or share objectionable content such as profanity, defamation, pornography, violence, or discriminatory remarks.

Zero tolerance: the Company may immediately suspend or permanently block accounts posting harmful content without prior warning.

Users may report harmful content using in-app tools. Within 24 hours of receiving a report, the Company will take appropriate measures such as removing content and blocking its author.

Users are legally responsible for their posts; the Company is not responsible for them.

Chapter 5. Paid Services, Withdrawal, Payments, and Refunds

Article 14. Paid Service Agreements

Some services may be paid, with prices and details shown on the relevant page. A Paid Service agreement is formed when the user follows the purchase procedure and completes payment. Minors need a legal representative’s consent; an agreement made without it may be canceled by the minor or representative, except that cancellation may be limited if deception caused the minor to be believed an adult.

Article 15. Payment and Subscriptions

Fees follow the Company’s pricing and are generally prepaid. Subscriptions automatically charge before the current period ends and renew access. For in-app purchases through Google Play, Apple’s App Store, or other marketplaces, payment, cancellation, and refunds follow that marketplace’s policies. The Company cannot directly intervene in marketplace payment systems.

Article 16. Withdrawal and Refunds — Important

Statutory withdrawal period: users may withdraw for a full refund within 7 days of payment if there is no usage history. Withdrawal may be restricted for:

  1. Content used or applied immediately after purchase, such as items or immediately viewable video.
  2. Used additional benefits, such as bonus points.
  3. Content lost or damaged for reasons attributable to the user.

For cancellation after 7 days or after use, the refund is calculated as follows:

Refund = amount paid − (actual days used × daily fee) − cancellation fee (10% of the amount paid).

The daily fee is based on the regular price before discounts. No refund is paid if the calculated amount is zero or less.

For marketplace purchases, including Apple App Store and Google Play, marketplace refund policies take precedence. Users must request refunds through that marketplace’s support, and the Company may lack authority to approve them.

Where termination is attributable to the Company, such as service suspension, only the amount for days used is deducted and the remainder is refunded.

Chapter 6. Termination and Restrictions

Article 17. Termination

Members may request termination at any time through account deletion in the Service. The Company must process it immediately under applicable laws. All member data is deleted upon termination except information retained under applicable laws or the Privacy Policy.

Uninstalling the app does not delete an account or cancel a subscription. Paid subscribers must cancel their subscriptions separately to stop future charges.

Article 18. Restrictions

For violations or disruption, the Company may progressively restrict use through warnings, temporary suspension, or permanent suspension. It may immediately impose permanent suspension for legal violations including identity or payment theft under the Resident Registration Act, illegal software or disruption under the Copyright Act, and unlawful communications, hacking, malware distribution, or exceeding access rights under information and communications network laws.

Members may appeal through the Company’s procedures. If the appeal is considered justified, access will be restored immediately.

Chapter 7. Damages and Disclaimers

Article 19. Damages

The Company is liable for damage caused to users through its intent or gross negligence. Users are liable for damage to the Company caused by violating these terms.

Article 20. Disclaimers

The Company is exempt from responsibility for inability to provide the Service due to natural disasters or equivalent force majeure. It is not responsible for disruptions attributable to users, the reliability or accuracy of information posted by users, or transactions between users or between users and third parties through the Service. It is not liable for free services unless applicable laws specifically provide otherwise.

Physical injury: as stated in Article 11, the Company assumes no responsibility for injury, illness, or other physical harm resulting from following exercise information provided by the Company.

Accuracy, completeness, reliability, currency, or fitness for a particular purpose of AI coaching or AI-generated Results is not guaranteed. The Company is not liable for loss from using them as a substitute for medical judgment or professional advice unless caused by its intent or gross negligence.

The Company is not responsible for the accuracy, legality, or infringement of rights in information entered into AI features. Unless applicable laws specifically provide otherwise, it is not liable for temporary limits or interruptions caused by outages, delays, errors, maintenance, or policy changes of AI models, cloud infrastructure, networks, or external processors.

Chapter 8. Miscellaneous

Article 21. Dispute Resolution

Electronic commerce disputes involving user requests for remedies may be submitted to mediation by an agency designated by the Fair Trade Commission or a city/provincial governor. The Company gives priority to justified complaints and opinions. If prompt handling is difficult, it immediately informs the user of the reason and expected schedule.

Article 22. Jurisdiction and Governing Law

Lawsuits concerning electronic commerce disputes are subject to the exclusive jurisdiction of the district court for the user’s address at filing, or residence if there is no address. If the address or residence is unclear, or the user resides abroad, jurisdiction is determined by the Civil Procedure Act.

Lawsuits between the Company and users are governed by the laws of the Republic of Korea.
